Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pinskia at gcc dot gnu.org --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I am suspecting it is the std::find changes (e.g r15-1857). I did hear that libc++'s usage of memchr was slowering for SPEC 2006 on aarch64 before and dealII is C++ code after all.
